Question

The snail moved 6 inches in 120 minutes. What was the average speed of the snail in inches per minute

1/20 of an inch
1/2 of an inch
2 inches
20 inches

Answer 1

Most likely 1/20 of an inch because letters C and D are irrelevant and if the snail moved 1/2 of an inch per minute, the snail would've travelled well over six inches within 120 minutes.

Answer 2

Option A.

Step-by-step explanation:

It is given that snail moved 6 inches in 120 minutes.

Distance = 6 inches

Time = 120 minutes

We need to find the average speed of the snail in inches per minute.

Formula for speed is

`Speed=(Distance)/(Time)`

Substitute Distance = 6 and Time = 120 in the above formula.

`Speed=(6)/(120)`

Cancel out common factors.

`Speed=(1)/(20)`

The speed of the snail is 1/20 inches per minute

Therefore, the correct option is A.
